Abstract The internal friction as martensite state is believed to be an M/Minterface one, which can be explained as an expression deduced from the theory ofdislocation internal friction. The internal friction in the region of martensitic trans-formation consists of two parts, including ones of the M/M interface and of thephase transformation. The later is further composed of two portions, the majorproduced by reverse martensitic transformation and the other from stress-inducedmartensite. It was also found that the degradation of dampling properties of theCuZnAl alloys is related to the dislocation, which is introduced from the excitingprocess, and tends to a stable value after certain excitements.

Key words: damping property CuZnAl alloy martensite martensitic transformation
